:UNITED STATES PATENT OFFIC JOHN H. MORRIS AND HENRY MORRIS, OF SEWARD, NEBRASKA, ASSIGNORS TO MAGGIE G. MORRIS AND HENRIETTA MORRIS, BOTH OF SAME PLACE.

COMBINATION-LOCK.

SPECIFICATION forming part of Letters Patent No. 437,658, dated September 30, 1890.

Application filed August 2, 1890.

To all whom it may concern:

Be it known that we, JOHN H. MORRIS and HENRY MORRIS, of Seward, Seward county, Nebraska, have invented certain new and useful Improvements in Combination-Locks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention relates to an improvement in combination-locks; and it consists in the peculiar combination and arrangement of devices hereinafter more fully specified and claimed. a

Our object is to provide a combination-lock to be applied more especially to private letter-boxes, &c., and is so constructed and arranged that if the owner forgets the combination he may attract the attention of the clerk in the' oflice, who by simply depressing the front end of a pivoted lever releases the latch and the door may be opened. I

Referring to the drawings, which illustrate this invention, Figure 1 is a view showing the outer face of thedoor, the combination being D O, as it is ready to be unlatchcd. Fig. 2 is a rear view of the same, showing in dotted lines the door unlatched'. Fig. 3 is a rear view of the lock, showing the combination lostand the door unlatched by the depression of the front end of the lever mentioned. Fig. 4 is a central vertical section of Fig. 1. Fig. 5 is a vertical section .on the line mac of Fig. 4,1001;- ing toward the rear of the door. Fig. 6 is a perspective View of the sliding boX carrying the pivoted lever. Fig. 7 represents face views of the disks V and E. v

Similar letters refer to similar parts in all the figures, in which A represents the door, from the rear side of which projects the lugs or pins 0, engaging in the vertical slots E of the sliding box' B. The face of the casing B is also provided with an elongated opening B, connected at its upper end with the slot P, from which extends upward and rests against the rear side of the door A the ear E. Securedin this upturned portion E is the rear end of a bolt or pin F,

which passes through the vertical slot a in the door and has secured on its forward end the button G. Pivoted at H on the inner side of the casingD is the lever I, the forward end of which passes through the slot J in the casing Serial No. 360,766. (No 11.0.1.1

L. Secured to the inner side of one of the vertical walls of the casing is a Inc; or projection M, around which is secured the rear end of a spring N, the forward upturned end 0 of which bears against the lower edge of the lever I. j

Secured in the rear wall of the door A, and projecting through the notch P of the casing B, is alug or projection Q, around which passes a spring R, the opposite end of which bears against the lower side of the lug or projection S, secured to the inner wall of the casing B.

Secured 0n the front side of the door, and provided with letters or numbers at intervals around its face, is the circular disk T, the barrel portion of which projects through an opening in the door, and also through the opening B of the casing B. The disk T is provided with the outstanding lugs or pins by which it is revolved. A shoulder 'u, is formed on the rear edge of the barrel-portion of the disk T, on which rests the disk V, and which is held in place by the washer W, which is secured to the rear end of the .barrel portion U of the disk T by means of the screws to.

Coiled round the barrel portion U of the disk T, and bearing at either end against the rear wall of the door and the face of the disk V,is the spring X. Resting-against the face of the disk T is the smaller disk Y, which is provided with numbers or letters onits face in radial alignment and-corresponding with the numbers or letters on the face of the disk T.

Castintegral with the disk Y, or which may be secured upon the same, is the projection Z. Projecting rearwardly from the disk Y, and passing through the cylindrical opening B of the barrel portion U of the disk T, and also through the opening in the washer W, is the shaft or projection A Spring-washers O and D are slipped over the end of said shaft A and bear on either side against the washer W and the disk E, which is secured round the shaft At after said washers O andD' are in place. I A key or pinF, passing through the end b, which is adapted to engage the notches 1;

and e in the periphery of the disks V and E when the door is unlocked. The door is also provided with a glass window H.

The operation of my invention is as follows: The revolving of the disksT by means of the small lugs or projections and of the disk Y by means of the hand-piece Z to the combination E and 0 causes the notches D and E in the peripheries in the disks V and E to pass into Vertical alignment with the projection U of the casing B,when the forcing of the button G downward in the slot at of the door causes the downward movement of the casing D, the projection b of said casing entering the aligned notches 'v and e, and the latch I, being secured to the casing D, is forced below the latch-block K, as shown in dotted lines, Fig. 2, when the door may be opened. If the owner forgets the combination he may attract the attention of the 1 clerk inside the oflice, who by depressing the forward end of the pivoted lever I by means of the lug or projection L unlatches the door, as will be readily understood, and which will when released return to its normal position by reason of the spring N,which bears against the under edge of the lever, extending its pressure upward. To change the combination, the projection b of the casing B is forced into the notches in the disks V and E when being held securely in position. The disks T and Y maybe turned to any combination desired, as will be readily understood. When the door is closing the upper forward edge of the lever I strikes the downwardly and rearwardly inclined edge of the latch-plate K, and is forced downward until it clears the rear edge of said latchplate, when the spring N immediately forces it upward in the rear of the plate K and the door is locked.

Having thus described our inven tion,what we claim as new, and desire to protect by Letters Patent, is
